How to add dark mode color to NSView layer color

Question

I've added a light mode color and a dark mode colour and set the color like this.

override func viewDidLoad() {
    super.viewDidLoad()
    titleLabel.textColor = .CP2
    view.wantsLayer = true
    view.layer?.backgroundColor = NSColor.myColor.cgColor
}

Regardless of dark mode and light mode, the color is always the Any Appearance color.
